Objective: To perform validation for an arm-type oscillometric TM-2655 device (A&D Company Ltd, Tokyo, Japan) for blood pressure measurement according to the British Hypertension Society protocol., Methods: Eighty-five study participants (33 men and 52 women) were included in the study. Mean age was 52.9+/-15.0 years, systolic blood pressure range was 84-208 mmHg and diastolic blood pressure range was 48-120 mmHg. For each participant, three readings of TM-2655 were compared with sequential auscultatory measurements by two trained independent observers. The observers used a calibrated mercury sphygmomanometer and dual stethoscope. The results were graded according to the British Hypertension Society protocol 1993., Results: The average difference between mercury sphygmomanometer and TM-2655 readings for systolic blood pressure was -1.0+5.2 mmHg (mean+/-SD) and for diastolic blood pressure -0.9+/-4.7 mmHg. The proportions of values agreeing to within 5, 10 and 15 mmHg were 72.5, 93.7 and 99.6% for systolic blood pressure and 78.8, 96.9 and 100% for diastolic blood pressure between the observers and the device (A/A British Hypertension Society grade)., Conclusions: The TM-2655 device achieved British Hypertension Society grade A/A and therefore can be recommended for blood pressure measurement in an adult population.

Objective: To perform clinical validation of the TM-2564G device for in-hospital blood pressure measurement according to the British Hypertension Society protocol., Methods: The tests were carried out on 85 patients aged 19-82 years (41 male patients, mean age 50+/-19 years) with systolic blood pressure 75-219 mmHg and diastolic blood pressure 43-117 mmHg (mean 142+/-33/85+/-20 mmHg). For each patient, three readings of the TM-2564G device were compared with simultaneous auscultatory measurements by two trained independent observers. The observers used a mercury-calibrated sphygmomanometer and dual stethoscope. The results were graded according to the British Hypertension Society protocol 1993., Results: The average difference was -1.85 mmHg for systolic blood pressure and -1.20 mmHg for diastolic blood pressure. The standard deviation of the difference between TM-2564G and the observers' results was 4.85 and 4.16 mmHg for systolic and diastolic blood pressures, respectively. Systolic blood pressure percentage of readings agreeing to within 5 mmHg was 75.7%, 10 mmHg 95.36% and 15 mmHg 99.6%, and for DBP 82.7, 97.6 and 99.8%, respectively., Conclusions: The TM-2564G device achieved A/A British Hypertension Society grade and can be recommended for in-hospital measurement of blood pressure.

Objective: To perform a clinical validation for a semi-automatic arm-type device UA-704 (A&D Company, Ltd., Tokyo, Japan) according to the British Hypertension Society protocol., Methods: Eighty-five study participants (37 men) were included. The mean age was 50.1+/-17.0 years, systolic blood pressure range was 79-212 mmHg and diastolic blood pressure range was 43-118 mmHg. For each participant, three readings of the UA-704 were compared with simultaneous auscultatory measurements by two trained independent observers. The observers used a mercury calibrated sphygmomanometer and a dual stethoscope. The results were graded according to the 1993 British Hypertension Society protocol., Results: The average difference between mercury sphygmomanometer and UA-704 readings was -1.85+/-4.26 mmHg (mean+/-SD) for systolic blood pressure and -1.44+/-3.97 mmHg for diastolic blood pressure. The proportions of values agreeing to within 5, 10 and 15 mmHg were 79.2%, 96.5% and 99.6% for systolic blood pressure and 86.7%, 96.9% and 99.6% for diastolic blood pressure for the observers and device (A/A grade for British Hypertension Society)., Conclusions: For an adult population, the UA-704 device for self-measurement of blood pressure achieved a British Hypertension Society grade A/A and therefore can be recommended for home blood pressure monitoring.

Peripheral vascular resistance, arterial blood pressure, and left ventricular hypertrophy (LVH) are closely related. In systemic hypertension, hemodynamic changes in systolic and diastolic function accompany LVH. Both of these cardiac functions are detected with echocardiography and were measured during this study in 23 essential hypertension patients treated with 2.5-5 mg of cilazapril daily for 6 months. Reduction in left ventricular mass was accompanied by an improvement in early diastolic filling pattern. This change in cardiac performance with cilazapril vasodilator monotherapy was characterized by a significant improvement in isovolumic relaxation time and normalized left ventricular early/atrial filling ratio.
